I just put two of these bad boys on my e-bike. Let’s see if I’ll make it to the office through snowy and icy bike lanes tomorrow! :)
And because someone already asked (not here!) — yes, spike tyres for bicycles are perfectly legal in Germany. At least for normal e-bikes like mine that go up to 25 km/h. For S-Pedelecs that go up to 45 km/h there might be different rules, though.

@jwildeboer

Cars with spikes are limited to 50kmh in Germany.

@Life_is @jwildeboer No, spikes are completely forbidden for cars in Germany. See §36 (1) StVZO. https://www.gesetze-im-internet.de/stvzo_2012/__36.html
§ 36 StVZO - Einzelnorm

Note to self: Grsetzbücher nicht mehr aus der grabbelkiste vor der buchhandlung mitnehmen.

@jwildeboer wondering, how convenient is to ride with those on normal roads, e.g. if temperatures surge for a few days, do you need to switch them out again immediately? Or can you just wait for a few days and see what the next days will bring?

@willemsst @jwildeboer

It helps to a certain degree to adjust the tire pressure.On dry roads I ride with high tire pressure, and when it's really icy, it helps to lower the pressure as much as possible. A second wheelset that can be changed quickly is of course ideal.

@Spieltag @willemsst I have a slightly simpler solution: a second bicycle with normal tyres ;)

@willemsst @jwildeboer In my experience they are rather inconvenient in normal conditions: high rolling resistance, noisy, slippery on metal and cobblestone.

As Jan already pointed out, best to have a separate winter bike in locations with only a few days of frost/snow per year. I use an old, rather crappy bike of mine for that, so no big cost involved.

@jwildeboer
You'll be safe with spikes. Just make sure you'll get used to them with slightly slower speeds. Especially taking curves feels a little different (at least on my bike without a motor and a light frame).
@jwildeboer Looking forward to hear about your experience. I always was thinking about getting some, but never had sufficient motivation to do the research so far...
@jwildeboer good luck 🤞
I hope for snow- and ice-free lanes tomorrow, I only have Marathon Mondial tyres. Learned the hard way a few weeks ago which corner is particularly dangerous 😬

@jwildeboer I haven't used them in last winter and this winter at all but I love the freedom they give when everybody else just slides!
